MILKING-MACHINE.

Application filed April To all whom it may concern:

'Be it known that I, OTTO C. SinILsKY, a citizen of the United States,and a resident of Algoma. in the county of Kewaunee and State oflVisconsin, have invented a new and Improved lililking-ll/lachine, ofwhich the following is a full, clear, and exact descrip tion.

This invention relates to dairy apparatus, and has particular referenceto thattype of devices known as milking machines or mechan'cal 'milkers.l

Among the objects of this invention are: to provide a machine of theclass indicated which will cause the milking operation to be performedby compression rather than by suction or stripping; to provide a deviceadjustable s0 to accommodate it for use in connection with differentsize cows or those having different size udders; to provide an actuatorfor the milker which is adjustable in accordance with the size of theteatsjand to provide a milking machine in which the compression cups areformed and operated so as to simulate the form and operation of apersonshand in hand milking.

The foregoing and other objects of the invention are accomplished in apreferred em bodiment of the invention by means of the mechanismhereinafter fully described and claimed and illustrated in theaccompanying drawings, in which- Figure 1 is a representation of one ofmy machines in actual use; Fig. 2 is a plan view of the machine; Fig. 3is a side elevation of the same; Fig. & is a sectional detail on theline 4-4 of Fig. 2; Fig. 5 is an outside elevation of one of thecompression cups; Fig. 6 is a transverse section on the line 6-43 ofFig. 5; and Figs. 7 and 8 are vertical sections showing differentpositions of the movable member of the cup.

' This invention com arises a frame 10 of any suitable curved orm, shownas comprising a plurality of sections adjustably connected each to eachby means ofclamps 11 and set screws 12. Extending diametrically acrossthe frame 10 is a support 13, likewise composed ofa series of sectionsconnected by means of screws 14, and the outer ends of said cross barare preferably connected to clamps 11 of the frame. A compression cup 15is supported by each of said frame sections, as by means of a screw 16.

Specification of Letters Patent.

Patented Aug. 20, 1912.

Serial No. 694,062.

Each of said cups is substantially tubular and comprises a fixed section15 and a movable section lfi 'provided with a roller in itsouter'face,said fixed section having a substantially rigid connectionwith the frame 10 as aforesaid. The here or inner surface of the cup 15is provided with a soft lining 17, preferably composed of rubber and forthe purpose of protecting the teat to be operated upon thereby and toprevent the same from slipping out of place. The normal tendency of saidlining 1.7 is to cause the two sections of the cup to approach eachother, but said tendency of the lining is counteracted by a spring 18 onthe outside tending to force them apart. The two cup members are pi\'-oted together on the sides by means of slides 19, each comprising aplunger pivotally connected to one of said members for the purpose ofpermitting a rolling action of the cup in operation and yet the form andarrangement of the hinge are such that the movable member of the cupwill have a lateral swing in addition to said rolling move ment.

Connected to the cross bar 15?, is an actuator 20, the same beingjournaled for rotation upon the cross bar and adapted to be driven byany suitable means, as for instance, a flexible shaft 21 driven from anysuitable source of power. The actuator 20 consists of a wheel orcylindrical body having upon its periphery a plurality of sets ofspring-pressed camsQQ and The cam 22 is placed above and slightly in adance of the companion cam 23, the cams being adapted to operatesuccessively upon the movable cup member 15 when the actuator is causedto rotate in the direction indicated by the arrow in Fig. 2. By virtueof this arrangement the cam 22 causes the upper end of the member 15* topress the teat at its upper end or root, and then, not releasing suchcompression, providing that the companion cam 23 will continue suchcompression progressively downward, simulating the action of a mans handin milking. Furthermore, the lower cam 23 is setat an inclination to theplane of the actuator so as to more completely'carry out the resultabove indicated and through the rolling motion of the movable cup member15 The cams 22 and 23 are thrust normally outward radially of theactuator by means of springs 24, and the effective operative position ofthe same may be varied through the adjustment nuts 25 in order to adjustthe same to the size of the teats or the hardness of the milking in eachcase.

The frame 10 is adapted to be held in proper position on the cows udderby means of a series of spring loops 26 con nected to the respectivesections of said frame, as indicated especially in Figs. 2 and 3.Furthermore, the entire machine is adapted to be supported in operativeposition by means of a strap 27 over the coWs hips and having branchesconnected to the 'frame at 28, such straps, of course, being adjustableto suit the size' of the cow. The pail for the milk may also besuspended front the same strap 27,

the cups is adapted to be'kept sanitary and to be directed therefrominto the pail by means of spouts 30 suspended or hooked upon the lowerends of the cups as at 31.

The several parts of this'machine may be constructed of any suitablematerials ac cording to the purpose thereof, and the relative sizes andproportions of the same ma be varied to considerable extent Withoutdeparting from the spirit of the invention.

Having thus described my invention, What I claim as new and desire to'secure by Letters Patent is In a milking machine, the combination of aframe, a plurality of compression cups, each of said cups being oftubular form and comprising relatively fixed and movable sections,.saidsections being connected along two edges by a slide, a spring tending toseparate said sections, and an actuator adapted to operate successivelyupon the opposite ends of said movable cup section against the tensionof said spring.

2. In a milking machine, the combination of a frame, a series ofcompression cups carried by said frame, being substantially tubular andcomprising relatively fixed and movable sections, a flexible lining forsaid cups tending to contract the same, a spring tending to separate thecup sections in opposition to said linmg, and an actuator including apair of cams adapted to successively operate upon if desired, as by"meansiof connections 29. The milk from each of said cups the oppositeends of said movable cup section.

3. In a milking machine, the combination of a frame, a series ofcompression cups connected to and carried by said frame, and

of cams pivoted thereto and adapted to opcrate successively upon theupper and lower ends of the cups, one of said cams being disposed at anangle to the plane of the other substantially as set forth.

4. n a milking machine, the combination of a frame, a plurality ofcompression cups carried thereby, in said frame, and a plurality of camsmovabl connected to the periphery of thewheel, said cams being adaptedto operate successively upon the cups, one. of the cams being inclinedat an angle to the plane of rotation of the Wheel. l

5. In a milking machine, the combination of a frame includin a crossbar, a series of compression cups'carried by the frame, an actuatorcomprising a wheel journaled on said cross bar, and a pair of cams pivanactuator cooperating with said cups and comprising a cylindrical bodyand a pair a Wheel pivoted for rotation otally and radially adjustablyconnectedable sections, the fixed sections being connected respectivelyto the aforesaid frame sections, an actuator comprising a wheeljournaled for rotation on said cross bar, and a set of cams carriedthereby and adapted to operate successively upon the movable. 'cupsections, tending ,to move the same toward the fixed sections in acombined rolling and slide movement. In testimony whereof I have signedmy name to this specification in the presence of'two subscribingwitnesses. OTTO .C. SIBILSKY. Witnesses:
